I am a newbie that has been around a little while.
I have only used 3 themes and tried 3 others (2 of which broke from neglect).
Weaver 2 is VERY WELL taken care of, which I really appreciate. It is very customizable with a forum to find answers.
It is so popular that there is a lot of information available all over google.
I particularly love that I can install my own header from my hard drive - easily.
color changes are easy as well
there are many options for sidebars
it is very widget friendly
and there are several child themes built in!
When I am ready for a paid theme, I will use the pro version, I love it that much!
This has been a real FIND!
Thank you for your hard work and your wisdom!!!! Mary
